Description
Technical field
This utility model is related to bridge construction field, and in particular to a kind of device for preventing small box girder internal model from floating.
Background technology
Small box girder as which is from heavy and light, construction is fast, Stability Analysis of Structures the advantages of, always Design of Highway Bridge is preferred.It is little
Box beam typically carries out prefabricated processing in precast beam field, and being then transported to scene carries out erection installation.In the mistake of prefabricated small box girder
Cheng Zhong, the fixation of small box girder internal model are one critical processes of concreting.It is whether accurate that internal model is fixed, and will directly affect
The thickness of the physical dimension of small box girder, particularly top board and base plate.
In practice of construction, often due to internal model is difficult to fix, when box beam bottom web concrete is poured, internal model receives coagulation
Soil extruding and produce a certain degree of floating, so as to cause the top board size of small box girder less than original design size, roof steel bar
The unqualified thickness lattice of protective layer.To solve this problem, people to adopt and press internal model in " π types " structure, to prevent which from floating.Short-term is come
See, effect is significant.But on long terms, on the one hand as concrete buoyancy is big, " π types " structure is easily bent, causes in internal model
It is floating；On the other hand as internal model top surface is acted on by larger concentration power always, cause internal model deformation very fast, have impact on the use of internal model
Life-span.
The content of the invention
This utility model provides a kind of for preventing small box girder internal model to solve technical problem present in known technology
The device of floating.The device can effectively solve the problems, such as that small box girder internal model floats, and affect less to internal model service life.
This utility model is adopted the technical scheme that by solving technical problem present in known technology：It is a kind of to be used to prevent
The device that only small box girder internal model floats, including upper laminated structure and pull-down structure, the upper laminated structure includes crossbeam, in the crossbeam
Two ends below be respectively provided with one with its affixed draw ring, the draw ring is connected with the upper end of flower basket bolt by drag hook, the gaily decorated basket
The lower end of bolt is connected with foundation bolt；Two supporting legs arranged along its length, institute are connected with the middle part of the crossbeam
State the top that supporting leg is pressed in internal model；The pull-down structure includes the pull bar being arranged between internal model bottom and beam making bench, described
Pull bar passes through the upper end of spilled water hole, the pull bar to adopt locking nut and backing plate to lock on the upper surface of internal model bottom, described
The lower end of pull bar is threadedly coupled with embedded nut, is connected with anchor bar in the bottom of the embedded nut, in the anchoring steel
Muscle and the embedded nut are provided with PVC head protectors, and the PVC head protectors, the embedded nut and the anchor bar are poured
Build in beam making bench, the PVC head protectors are located at the lower section of pedestal steel plate.
The drag hook and the flower basket bolt are vertically arranged.
The draw ring is the semicircular ring affixed with the crossbeam.
The drag hook is simmered using reinforcing bar.
This utility model has the advantages and positive effects that：The double-direction control measure of " upper pressure is drawn ", pull bar is taken to lead to
Cross small box girder bottom water drain hole to be connected internal model with beam making bench, reduce internal model stress center of gravity, internal model is enhanced in concrete
Stability in casting process, and most buoyancy are transferred on beam making bench by pull bar is drop-down, reduce internal model top
Portion's stress, it is ensured that the service life of internal model.This utility model can also make small box girder inner structure size be effectively controlled, work
Cheng Zhiliang obtains effective guarantee, with good Social and economic benef@, has promotion prospect in bridge construction.
